The Doppler WR7 exhaust has slowly been replacing the earlier ER1 systems although the WR7 expansion still keeps with a very similar design. Boasting the latest WR7 silencer design and impeccable performance through a very broad RPM range, the WR7 is a serious contender to many other systems on the market whether you’re using it on a 50cc or tuned 80cc machine. Suitable for all Aprilia RS 50 models up to 1999.
